D5 D5        C5
   You make me smile
D5 
Baby
D5             C5
Uhm , you make me smile

D5
I think it's safe to say
C5
things just haven't been going my way
D5
No work coming in so my money's spent
C5
and I still got bills to pay
But all in all you been right here with me
When I'm sinking, oh, you come through and lift me
It's nothing more then the love that you give me
keeps me from drowning in tears

CHORUS
            D5
You make me smile
F5
   oh, you make me smile
            C5
You make me smile
   Come through and save the day
            D5
you make me smile
F5
   you make me smile
            C5
you make me smile
   in a very special way

D5
Everywhere I go people seem to ask me
C5
where I'd get my joy, why am I so happy
D5
In these trying times when a frown is the fashion
C5
I'm beaming like the sun now how can that be
See the answer to the query is very simple
I'm always grinning from dimple to dimple
Because you love me unconditionally
my happiness is heartsake, can't you see

            D5
where do we go
   Can't you see when you're gone girl
                        C5
When you gonna wait for me
   I just don't know what to do
Don't know what to do
D5
Everything about you girl
C5
everything revolves around you

CHORUS
            D5
you make me smile
       F5
   for makin' me smile
                C5
oh, you make me smile
   came through and saved the day
            D5
you make me smile
               F5
   you make me smile
            C5
you make me smile
   in a very special way
you make me smile
   you make me smile
you make me smile
   love it how you made me hold my head up high
you make me smile
   you make me smile
you make me smile
   feel I got evolved in the sky
you make me smile
   when nothing's going my way, what else can I say
you make me smile
   when I can't see the light here you come shinin' bright
you make me smile
   when everything's bad and I'm feelin' real sad
you make me smile
   when I don't have the answers you always give me a chance to
you make me smile... smile... smile
